[目的]探索明水1号在彰武区域氮磷钾肥的最佳施用量，为实现甘薯增产增收提供施肥技术指导。[方法]通过氮磷钾三要素不同施肥水平试验，研究施肥量与明水1号甘薯薯蔓比、产量关系。[结果]氮磷钾施肥水平高低与甘薯薯蔓比、甘薯产量成正相关；在氮磷钾肥配施情况下，随着施肥量的增加，薯蔓比随之增加，甘薯单株产量也增加，最佳施肥量为尿素225 kg/hm2、过磷酸钙900 kg/hm2、硫酸钾225 kg/hm2。[结论]该研究可为明水1号甘薯在彰武县的种植提供参考依据。

The aim was to study the superior ratio of N,P,AND K. These would provide technical guidance for increasing sweet potato yield in Zhangwu area. [Method] According to the different fertilizer level, the relationship of tuber vine ratio and yield were studied. [Result] The results showed that it was positive correlation between N, P, K fertilizer and sweet potato vines and yield; On the condition of NPK fertilizer combined application, the sweet potato vines ratio and the per production increased with the increase of fertilizer rate. The best fertilizer rate was carbamide 225 kg/hm2, calcium superphosphate 900 kg/hm2, and potassium sulphate 225 kg/hm2 [Conclusion] This study provided the reference basis for Mingshui No.1 in Zhangwu area.
